What's the repository link? I think it would be fascinating to have a corpus of "hacked" solutions like this. Can't tell you how many times a couch co-op game night got sabotaged by some piece of hardware failing to communicate with another.
The "linux" support is pretty narrow (because I made this for myself). It's restricted to SteamOS. But I'm sure it could be ported easily, the repository contains documentation about the important parts from reverse engineering the firmware.
